The RF Cook story.

R.F. Cook Manufacturing Company was founded in 1944 by Ray Cook in Cuyahoga Falls, Ohio. From the beginning, R.F. Cook focused on the tough jobs that nobody else wanted to do. The company built a reputation for quick-turnaround, close-tolerance machining using carbide and other exotic materials. In 1969, R.F. Cook built an 18,000-square-foot, climate-controlled manufacturing facility in Stow, Ohio. In 2015, an additional 4,500 square-foot, climate-controlled clean room was added. The company continues to expand and prosper serving a growing group of worldwide customers in a variety of industries.

From the beginning, R.F. Cook focused on the tough jobs that nobody else wanted to do.

When Ray retired in 1986, Pete LeVan bought the company and continues the tradition. Today, R.F. Cook combines old-fashioned machining know-how with state-of-the-art manufacturing technology to offer you a one-stop solution like no other. “Our customers call it ‘multiplicity,’” explains Pete. “With our specialty in low-volume, close tolerance-machining and grinding, R.F. Cook supplies tooling, inspection gauges, assemblies, replacement parts, repair services, cryogenic processing, and more.” One look at our equipment list and you will see the broad scope of our capabilities. And, behind our modern equipment stands a talented workforce with decades of manufacturing experience. This is truly a powerful combination that delivers quality and value second to none.

What's new at RF Cook.

waterjet cutting machine

New Precision Waterjet Cutting at RF Cook

February 2020

RF Cook has added waterjet cutting to our growing list of precision manufacturing services. Our new, American-built WARDjet A-0612 Waterjet Cutting Machine features powerful abrasive waterjet cutting with incredible speed and accuracy on virtually any material up to 7.0” thick. The cutting envelope is 24” x 48” with a linear positional accuracy of +- .003” and repeatability of +-.002” and cutting speeds up to 500 inches/minute. Waterjet cutting is ideal as a cold abrasive process that delivers precision, net-shape results with no heat-affected zones and no material hardening or distortion.

The addition of waterjet cutting represents a significant expansion of our already robust list of manufacturing options. Whether used as a stand-alone process or in conjunction with our CNC machining operations, waterjet cutting can save you time and money on your next requirement. Contact us to learn more about the cutting-edge precision manufacturing options now available at R.F. Cook Manufacturing Company.
